Money changes you

Phil Anderson finishes his classic More is Different article from Science in 1972 with the cheeky and amusing conclusion:

Marx said that "Quantitative differences become qualitative ones." But a dialogue in Paris from the 1920’s sums it up even more clearly:

FITZGERALD: The rich are different from us.

HEMMINGWAY: Yes, they have more money.

I often wondered what this was all about. It is worth reading Quote/Counterquote which explains that the dialogue never actually happened.
